How-to Create a Dog Patch (Backyard Dog Pee Area)

Eight years ago after we brought home our first Labrador Retriever we wanted to have a place for her to do her business with out brown spots or land mines in our back yard. We created a area for her to use and trained her to go in only that location. We have two labs and this patch is just the right size for 2 large breed dogs. The patch has has evolved over the years we are on the 4th version.

  • Version 1.0 
    • Let her do her business in one location on grass. Kills the grass and starts to smell quickly.
  • Version 2.0 
    • Doug out a 6' x 4' x 0.5' (l by w by d). 
    • Filled in the hole with 3-4 inches of pea gravel.
  • Version 3.0
    • Version 2.0 had issed with flooding in during hard rain
    • The grade in our yard allowed for the addition of a PVC "pluming" line to drain the patch
  • Version 4.0 (Described below)
The problem with using 3-4 inches of pea gravel is that it tightly packs and after enough runoff from the surrounding ground dirt enters the patch and it begins to hold more water and bacteria (smelly).

The patch before attacking this project looked a bit worn and used. The pea gravel is fairly well packed together.

The patched needed to be taken down to the bare bones. You can see that on the ground is weed block to keep the pea gravel from mixing into the floor of the patch. There was also some rock to allow drainage to the back of the patch to facilitate the travel of the water to the PVC pipe. 

The dig.
The basic building blocks of the version 4.0 patch are:
  1. Dig a hole - depth depends on the grade of your yard and the ability for it to drain on its own or with the help of pluming.
  2. Line it with something to hold back the dirt. We chose 6 inch deep by 8 inch long solid rock from a home improvement store.
  3. Grade the bottom of the hole so water and pee flows to the drainage point. In our case it is to the back of the patch.
  4. Line the bottom of the hole with weed block or a similar material. I don't know if I would use plastic but you could experiment with it.
  5. Add in 2 to 3 inches of river rock for ponds. This can be purchased in bags at your local home improvement store. Our patch is ~16 sq feet so it required 7 bags.
  6. Add a mesh screen on top of the river rock. You can use mesh screen that is used to replace the screen in windows.
  7. Add 1-2 inches of pea gravel on the mesh screen. This allows for water to drain but keeps the pea gravel from filing in the cracks of the river rock. It also allows for easy removal of the gravel should it need to be replaced at a future date after a few years of use.

To help maintain the health of the patch I recommend flushing it periodically with a vinegar solution. Vinegar has antibacterial properties and it can be used to keep any bacteria that may grow in the patch in check - Your pets are using this as a bathroom and from experience bacteria will begin to grow if not kept in check.

... and here is the completed patch. I added a garden border to keep excess runoff with dirt from entering the patch.

If you have everything you need this project can be completed in a day. 

The updated patch has been tested and dog approved!
